METROPARKS OF THE TOLEDO AREA GOVERNING POLICIES The following polices governed the development of the 2016‐2017 deer management plan: POLICY: THE MISSION OF THE METROPOLITAN PARK DISTRICT The mission of Metroparks of the Toledo Area is to conserve the region’s natural resources by creating, developing, improving, protecting, and promoting clean, safe, and natural parks and open spaces for the benefit, enjoyment, education, and general welfare of the public. Board Policy #: 1 Resolution #: 60‐01 Approved: August 15, 2001 Resolution #: 58‐08 Approved: July 16, 2008 Resolution #: 79‐14 Approved: June 4, 2014 POLICY: STEWARDSHIP OF PARKLANDS Every activity of the Metropolitan Park District of the Toledo Area is subordinate to its duty to faithfully preserve the public parklands for future generations in essentially their natural state. Ongoing research has identified significant representative areas that contain rare and endangered plants, animals, and natural features within the Metroparks, including the Oak Openings Eco‐region, Lake Erie Coastal Marshes, Maumee River Alvar Ledges, the Great Black Swamp, Oxbow/Floodplain/Riverine Wetlands and prairies, Glacial Groove and Fossil Bedrock Outcroppings, as well as wet prairie. These natural areas are land and water resources where natural processes are sustained through active best management practices with a goal of sustaining and enhancing the natural biodiversity and global connection of these representative areas of Northwest Ohio. Where significant cultural resources are present in natural areas and are worthy of preservation for their historic value, they shall be protected and presented for public appreciation and enjoyment to an extent compatible with the mission of the park district. The Metropolitan Park District of the Toledo Area will provide a leadership role in cooperation with other public and private agencies, and private landowners to preserve significant natural, historic, and cultural areas to enhance the quality of life within the northwest Ohio region. The purpose, significance and mission statement for each Metropark are attached and made a part of this policy. Board Policy #: 4 & 5 Resolution #: 59‐02 Approved: August 21, 2002 Resolution #: 58‐08 Approved: July 16, 2008 ‐ 2 ‐ B. WILDLIFE MANAGEMENT PHILOSOPHY AND PLANNING FRAMEWORK The following management philosophy and planning framework were used to guide the development of the 2016‐2017 deer management plan. 1. PROBLEM OF OVERABUNDANCE OF WILDLIFE POPULATIONS The Northwest Ohio landscape has been irrevocably altered by humans. Human‐ induced changes to natural land cover have impacted populations of native and nonnative wildlife species, some negatively and others positively. Those species whose populations increase within the human‐dominated landscape typically share one or more of the following traits: a) They tend to be habitat generalists which benefit from increased amounts of habitat edge associated with large‐scale habitat fragmentation caused by human‐induced land‐use change. b) They are well adapted to living in suburban and exurban landscapes typically resulting from sprawl‐type land development. c) They are relatively free from pressure from top predators which are largely absent from these human‐dominated landscapes. d) They benefit from a lack of human controls on their population (such as hunting or trapping) which are largely absent from urban areas where such activities are not permitted. 2. DEFINING CARRYING CAPACITY: Wildlife species exhibiting one or more of the above characteristics pose an increased risk of exceeding their biological, cultural, and/or ecological carrying capacities and may pose significant threats to native ecosystems including: a) Excessive direct predation on desired native plant and/or animal species b) Loss of habitat for desired plant and/or animal species, especially those that are rare, threatened or endangered c) Spread of wildlife diseases associated with high population densities Within the context of this management plan document, the following definitions apply: Biological Carrying Capacity: the maximum population size of a given species that can be supported within a set geographic area. Populations in excess of the biological carrying capacity can cause long‐term degradation to the health of the species and its habitat. Cultural Carrying Capacity: the maximum population size of a given species that can be supported within a set geographic area based on locally accepted cultural values and norms. ‐ 3 ‐ Ecological Carrying Capacity: the maximum population size of a given species that can be supported without adversely impacting populations of other native plant and animal species. It is important to note that ecological carrying capacity may be exceeded even when biological and/or cultural carrying capacities are not. 3. WILDLIFE MANAGEMENT PLANNING FRAMEWORK In keeping with Board Policies 1, 4, and 5, management of overabundant wildlife populations should be done in a manner that is safe, ethical, legal, and in accordance with currently accepted best management practices. Management of overabundant wildlife populations should be considered under one or both of the following scenarios: a) Ecologically‐based wildlife population management: Should be considered when a given animal population exceeds its biological and/or ecological carrying capacity as evidenced by appropriate ecological indicators such as: Widespread declines in the health of animals within the population Excessive loss of other desirable native plant or animal species due to direct predation from animals within the population Overall declines in ecological condition or native biodiversity associated with overabundance of animals within the population b) Situational wildlife population management: Should be considered when the cultural carrying capacity of a given species is exceeded resulting in a significant negative impact on park visitor experience such as: Excessive animal waste occurring on lawns or developed areas where visitors congregate Damage to the park district’s built infrastructure. C. WHITE‐TAILED DEER ECOLOGY AND POPULATION TRENDS The white‐tailed deer (hereinafter “deer”) is a native wildlife species occurring in every Ohio county and throughout the eastern United States. Deer are highly adaptable, utilizing a variety of habitats but are especially well suited for forested habitats near forest edges where buds, stems, and leaves of woody and herbaceous plants are abundant (PDCNR 2013). Deer are generalist herbivores, consuming a wide range of woody and herbaceous plant species and plant parts with specific dietary preferences varying by season and habitat (USDA 2014). Deer have an innate ability to preferentially select plants and plant parts that provide the greatest nutritional value for the least physiological cost (Berteaux et al. 1998). An individual deer typically consumes three percent of its body weight per day (Curtis and ‐ 4 ‐ Sullivan 2001), thus a single 200‐pound adult deer consumes roughly 6 pounds of vegetation each day. Deer are polygamous (i.e., a single male breeds with multiple females), breeding from October to January with peak breeding activity occurring in early to mid‐November. Gestation averages 200 days with most fawns born from late May through mid‐June. Fawns are weaned at 10 to 12 weeks and female fawns are capable breeding within their first 6 months. Life expectancy averages two years for males and three years for females in the wild, though individuals may live up to 15 years. In Ohio, adult males typically weigh 130‐ 300 pounds while adult females typically weigh 90‐210 pounds (ODNR undated). The reproductive potential of Ohio’s deer herd is extremely high. In western Ohio, over 50% of fawn does become pregnant, while pregnancy rates of yearling and adult does exceed 90%. Over 70% of yearling and adult does give birth to twins while 10% of adult does give birth to triplets (Tonkovich et al. 2004). Recruitment and mortality estimates show that Ohio’s deer herd is capable of a 50‐65% net population increase from the spring pre‐fawning period to the fall pre‐hunting period (Stoll and Parker 1986). As an example of the high reproductive potential of deer, in the University of Michigan’s 1,100‐acre fenced George Preserve an introduced population of six deer grew to 222 individuals in seven years (McCullough 1984). Over the past century, the Ohio deer population has exhibited an exponential growth rate since
